   NOTES
   ─────
   • --color-accent is unified to #801f6c (from variables.css).
     Original index file had #7e1d6b — change --color-accent
     in variables.css if you need to adjust the index shade.
   • .swiper-navigation-icon "color: rotate(180deg)" is a known
     bug preserved from the original.
   • div[id$="-items"] had two height values (470px vs 500px);
     500px is used here as the later/intended value.
